zorya: Skill for Claude Code

.claude/skills/add-slack/SKILL.md

add-slack is a skill for Claude Code from mihaipora/zorya. It costs 29 tokens per session (2,123 once invoked), scanned A, a copy of add-slack, MIT.

A setup skill that adds Slack, a team chat platform, as a NanoClaw channel. It applies the code changes and guides you through connecting a Slack app using Socket Mode, which does not require a public web address.

In plain words
What is it for?
Use it to add Slack messaging to NanoClaw, configure the required bot and app tokens, and choose the active channels.
Why use it?
It avoids manual integration work and helps you decide whether Slack replaces WhatsApp or runs alongside it. Socket Mode also suits setups that cannot expose a public URL.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

add-slack scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

The scan reads SKILL.md. This mod also ships 6 executable files (add/src/channels/slack.test.ts, add/src/channels/slack.ts, modify/src/config.ts, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Add Slack Channel

This skill adds Slack support to NanoClaw using the skills engine for deterministic code changes, then walks through interactive setup.

Phase 1: Pre-flight

Check if already applied

Read .nanoclaw/state.yaml. If slack is in applied_skills, skip to Phase 3 (Setup). The code changes are already in place.

Ask the user

  1. Mode: Replace WhatsApp or add alongside it?

    • Replace → will set SLACK_ONLY=true
    • Alongside → both channels active (default)
  2. Do they already have a Slack app configured? If yes, collect the Bot Token and App Token now. If no, we'll create one in Phase 3.

Phase 2: Apply Code Changes

Run the skills engine to apply this skill's code package. The package files are in this directory alongside this SKILL.md.

Initialize skills system (if needed)

If .nanoclaw/ directory doesn't exist yet:

npx tsx scripts/apply-skill.ts --init

Or call initSkillsSystem() from skills-engine/migrate.ts.

Apply the skill

npx tsx scripts/apply-skill.ts .claude/skills/add-slack

This deterministically:

  • Adds src/channels/slack.ts (SlackChannel class implementing Channel interface)
  • Adds src/channels/slack.test.ts (46 unit tests)
  • Three-way merges Slack support into src/index.ts (multi-channel support, conditional channel creation)
  • Three-way merges Slack config into src/config.ts (SLACK_ONLY export)
  • Three-way merges updated routing tests into src/routing.test.ts
  • Installs the @slack/bolt npm dependency
  • Updates .env.example with SLACK_BOT_TOKEN, SLACK_APP_TOKEN, and SLACK_ONLY
  • Records the application in .nanoclaw/state.yaml

If the apply reports merge conflicts, read the intent files:

  • modify/src/index.ts.intent.md — what changed and invariants for index.ts
  • modify/src/config.ts.intent.md — what changed for config.ts
  • modify/src/routing.test.ts.intent.md — what changed for routing tests

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
